Extra chargers can be picked up fairly cheaply on Amazon or eBay if you shop around. I bought four new Samsung chargers for my Google Samsung Nexus S and keep one at work, one in my bedroom, one in the living room, one in my laptop bag. My wife's phone and headset can use the same charger (micro USB) so we have spare chargers for all but my headset (a BlueParrott Road Warrior) that uses a different charger. But I have tried whenever possible to keep all my devices compatible with the micro USB standard for charging. And don't get the cheapo generic chargers, get the good ones. Samsung seem to be the best, some chargers will damage the cell phone. Notably, the original charger for my wife's headset (don't recall brand) damages phones; I trashed it.
